Where Should Your Heat Pump Be Located?

Air source heat pumps (ASHP) are becoming more common in UK homes, offering an energy-saving alternative to traditional gas boilers. Choosing the best location for air source heat pumps can make a real difference in performance. Here’s everything you should consider before installation, so your ASHP works smoothly from day one.

Best Location for an Air Source Heat Pump

The best location for an air source heat pump is outside, in a spot with good airflow and minimal obstructions. The ground should be level, and the area must have enough space around the unit to allow airflow to circulate without being blocked by walls, fences or furniture.

Commercial Air Source Heat Pump Placement 

Since commercial buildings have higher heat demands than domestic areas, the units are typically larger and heavier. Because of this, the pumps may be placed on rooftops, in designated plant areas or on reinforced concrete pads. The ground needs to have enough structural support to hold the weight of the unit.

You’ll likely need planning permission for commercial setups due to the size and impact of the equipment. It’s also crucial that the system is easily accessible for engineers to carry out regular servicing.

Domestic Air Source Heat Pump Placement 

For homes, heat pumps should also be located outside, ideally in a quiet, shaded spot. There needs to be enough space around the pump to ensure it’s accessible for installers and engineers to work on.

It should also be placed away from bedrooms and neighbours’ windows to prevent sound disturbance.

What Needs to Be Installed With an Air Source Heat Pump? 

Your heat pump is more than just the unit you see. Alongside the outdoor structure, your setup also includes components like:

• Interior and exterior coils
• Expansion valves and fans
• Hot water cylinders
• Pipework that connects the indoor and outdoor units
• Electrical wiring and controls

Every component helps your air source heat pump do its job effectively – heating your home in an energy-efficient way.

Considerations About Air Source Heat Pump Placement 

It’s not just space you need to think about during installation. Here’s what you should keep in mind before choosing the best location for your air source heat pump.

Noise and Neighbours

Heat pumps produce a certain level of sound while running, so it’s important to place the unit away from windows and outside seating areas to minimise noise impact. Try to install the heat pump at least one metre away from property boundaries and try anti-vibration mounts to control noise.

Size 

Larger units will need more space and enough room for air to flow around the pump. Don’t try to cram the unit into a small space just to keep it out of sight, as the lack of airflow may affect the operation.

Property Type 

The type and size of your property will also affect where the unit should go. Although ASHPs are generally suitable for all types of properties, but it is best to get professional advice for properties with space limitations such as flats or terraced houses. Semi-detached and detached homes are usually appropriate, as well as off-grid homes with their own renewable energy sources.

Ground or Wall Mount

Although some heat pumps can be wall-mounted, it’s not usually recommended. This is because vibration can make its way into the building and create unwanted noise. Ground mounting is more common, as long as the surface is level and well-drained to avoid water spillages.

Heat pumps can be installed on the ground or wall-mounted using specialist kits with anti-vibration feet. While wall-mounting carries a risk of noise transferring into the house, it’s usually minimal. If ground-mounted, the surface must be level and well-drained to prevent water spillages. 

Ventilation 

ASHPs need a constant flow of air to operate efficiently. Ensure the vents around the pump aren’t blocked by buildings, fences, plants or other structures as this can lead to poor performance. Overheating can cause component damage and actually increase energy consumption.

Accessibility 

To keep your heat pump performing as it should, regular maintenance and servicing is crucial. Engineers and installers will need enough room to access all sides of the pump to carry out checks and repairs if necessary.

What are the Rules Around Air Source Heat Pump Locations? 

Most domestic heat pump installations fall under permitted development, so you most likely won’t need planning permission. Your installer should be HVAC qualified and follow the guidelines of the MCS (microgeneration certification scheme). This includes clear standards to support the installation of air source heat pumps to ensure safety and legal compliance.

If you’re unsure where the best location for an air source heat pump is, contact our team and we’ll make sure you’re all set up for a safe and compliant heat pump installation. If your property is in a conservation area, it’s a good idea to contact your local planning authority to check the specific rules for your situation.

Where Should You Not Put an Air Source Heat Pump? 

You should avoid placing your ASHP in the following areas:

• In tight corners with poor airflow
• Directly under windows
• Close to outside seating areas
• In a non-accessible or locked area
• On hills or slopes
• Next to living areas or bedrooms

Your Heat Pump Location Checklist 

In summary, the best location for air source heat pumps is a well-ventilated, easily accessible area. Whether you’re installing a unit at home or in a commercial building, planning ahead and working with an expert team ensures your system runs efficiently for years to come.
